O.k. I see where you are going, and yes, that is an important feature but then, at least for me, the _description_ of the requirement is not clear (enough). A first shoot at it could be:

[[[
The fundamental requirement on identification already states that there should be a way to uniquely identify a publication (see 2.2.2 Uniquely Identifying a Web Publication). This requirement can easily be extended to constituents of a Web Publication by using standard Web identifications. However, a model that would extend this identification to the resources contained in a <em>Packaged</em> Web Publication is also necessary, making it possible to refer to a resource regardless of whether the resource is within an Web Publication or within its packaged version.
]]]

The requirement definition could also be a bit re-written, trying to remove the reference to a manifest.

[[[
A Portable Web Publication should include a a mapping of the identification of a constituent resource between the Web and its equivalent in a package.
]]]

WDYT?

Ivan

When it is packaged (and brought “off the web”), the person packaging it up wants everything self-contained but also can’t modify the original content (eg. an archival scenario).  As such, the resource needs to be included in the package but somehow the remote URL needs to now refer to an internal URL.

The identification case is about the PWP itself (aka the “single unit”), whether packaged or not.  The manifest/links section is about working with constituent resources (2.2.7) of the PWP when packaged.

This requirement should be extended to resources within a publication, such as a chapter, an image, or a mathematical formula. While the Web provides a model for this for non-packaged resources, a model that will work for the packaged version is also necessary.

Section 4.2 <http://w3c.github.io/dpub-pwp-ucr/index.html#limiting_features> “Limiting a Web Publication's Features” and Section 4.3 <http://w3c.github.io/dpub-pwp-ucr/index.html#escalating_trust> “Escalating Trust”: Upon re-reading this, please clarify what these use cases and requirements provide that the section on Horizontal Dependencies does not provide. I believe that we have successfully made a case outlining Accessibility use cases that are less than clearly defined in the Web world. Perhaps it is my lack of familiarity with security issues, but these security examples are rather fuzzy to me, and I think we need to better define them.
